ASP.NET 5(formerly ASP.NET vNext)

Lean .NET stack for building modern web apps

Telerik Academy Plushttp://academy.telerik.com

Visual Studio 2015 and ASP.NET 5

Caution At the time of this presentation, we are using KRE-CLR-x86 1.0.0-beta1 (ASP.NET 5 beta 1) As things are moving really fast in

this new world, it’s very likely that the things explained here will have been changed as you read/watch

Also this lecture requires good knowledge of the ASP.NET MVC technology

Introduction to ASP.NET 5

Introduction to ASP.NET 5

Lean .NET stack for building modern web apps Built from the ground up

Unified programming model that combines MVC, Web API, and Web Pages

Consists of modular components with minimal overhead

Open source in GitHub from the biginning https://github.com/aspnet/Mvc

Changes based on customer requests and feedback

Introduction to ASP.NET 5

Lean .NET stack for building modern web apps New flexible and cross-platform

runtime

New modular HTTP request pipeline

Cloud-ready environment configuration

Ability to self-host or host on IIS

Ability to see changes without re-building the project

Side-by-side versioning of the .NET Framework

New tools in Visual Studio 2015

7

What is Different in ASP.NET 5?

Flexible, Cross-Platform In the past, the .NET Framework was delivered as a single, all-encompassing installation Features were added but rarely

removed

The size of the framework continually grew

ASP.NET 5 can be run on Full .NET CLR – 200 MB, update

everything Best for backward compatibility

Core CLR (cloud-optimized runtime) – 11 MB Include only those features that you

need Cross-Platform CLR – Not ready, yet.

Use Mono.

9

Choosing Runtime By default, new Visual Studio projects use the full .NET CLR

You can specify the Core CLR in the configuration properties for your project

10

Demo: Different RuntimesASP.NET 5 (CLR) and ASP.NET Core 5

(CoreCLR)

Flexible, Cross-Platform (2)

ASP.NET 5 – Faster Development Cycle Features are shipped as packages

Use just features needed

Framework ships as part of the application

Zero-day security bugs patched

Same code runs in development and production

Edit code and refresh browser Develop with VS, third-party or cloud editors

12

Host Anywhere The ASP.NET 5 applications can be deployed on IIS or can be self-hosted (in own process)

If Core CLR is used every single dependency is bundled within the deployment package Not dependent on .NET framework

version

Different versions of .NET side-by-side Different applications may work

on different runtime versions

To run different versions,you must target the Core CLR

13

Better Performance Faster startup times Lower memory The platform (ASP.NET 5) is modular You can turn features on and off as

you want

14

Package Management ASP.NET 5 introduces a new, lightweight way to manage dependencies in your projects No more assembly references

Instead referencing NuGet packages

project.json file

15

Middlewares Improved HTTP performance

New HTTP request pipeline that is lean and fast The new pipeline also supports OWIN

You choose what to use in your application By registering middlewares

public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerfactory){ app.UseErrorHandler("/Home/Error"); app.UseStaticFiles(); app.UseIdentity(); app.UseMvc(routes => ...)} 16

Custom Middleware Create middleware class

Register in Startup.cs (IApplicationBuilder)

public class AppHeaderMiddleware { private readonly RequestDelegate next; public AppHeaderMiddleware(RequestDelegate next) { this.next = next; } public async Task Invoke(HttpContext context) { context.Response.Headers.Append("X-Application", "ASP.NET 5 Sample App"); await this.next.Invoke(context); }}

app.UseMiddleware<AppHeaderMiddleware>();// Register before app.UseMvc(...);

17

Demo: Custom Middleware

Other Improvements Made cloud-ready

Configuration, session and cache

No code changes for cloud environments

Dependency injection is built into ASP.NET Register services in Startup.cs

public void ConfigureServices(IServiceCollection services){ // ... services.AddScoped<ITimeProvider, TimeProvider>();}

19

Demo: IoC in ASP.NET 5

Grunt and Bower in ASP.NET 5

Visual Studio 2015 is integrating with Bower Similar to NuGet for client side

packages JS libraries and CSS packages

Integrating with Grunt Provide build tasks for client-side

purposes

Similar to MS Build for the client side Compile LESS, SASS

Bundling

Minification, etc.

21

Demo: Grunt and Bower in Visual

Studio 2015

View Components Similar to partial views, but much more powerful Something like mini-controller Responsible for rendering a chunk Some examples for view

components usage: Dynamic navigation menus Tag cloud Login panel Recently published articles Sidebar 23

View Components (2) Consists of two parts:

The class (derived from ViewComponent)

The Razor view located in: /Views/Home/Components/SideBar/

Default.cshtml or

/Views/Shared/Components/SideBar/Default.cshtml

More information www.asp.net/vnext/overview/aspnet

-vnext/vc

public class SideBarViewComponent : ViewComponent { public IViewComponentResult Invoke(int numbers) { return View(); }}

24

Demo: View Components

Web API in ASP.NET MVC 6

MVC, Web API, and Web Pages are merged into a single framework called MVC 6 This merging removes duplication

In ASP.NET MVC 5 there are overlapping features with different implementations MVC routing –

System.Web.Mvc.Routing

WebAPI routing – System.Web.Http.Routing

Currently only MVC and WebAPI are unified Web Pages will be added in a later

release

26

Demo: Web APIin ASP.NET MVC 6

Entity Framework 7 New platforms (in addition to .NET)

Windows Phone, Windows Store ASP.NET 5 (.NET core) Mac and Linux

New data stores (in addition to relational) Non-relational data stores Not a magic abstraction but option

to use common EF functionality in all data stores SQL Server, SQLite, Azure Table

Storage, Redis, In Memory (for testing)

28

ASP.NET WebForms 4.6 HTTP/2

Roslyn Code Dom Compilers Leverage the new C# 6 features

Async Model Binding (Leverage EF async)
